Which it's which pls help me

Answers

Answer 1

Answer: P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure

P: High melting and boiling points - R: the bonds in metals are very strong

P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.

P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily

What the guy said on top he is right.

Consider the following reaction: CO(g)+2H2(g)⇌CH3OH(g). The reaction between CO and H2 is carried out at a specific temperature with initial concentrations of CO = 0.29 M and H2 = 0.51 M. At equilibrium, the concentration of CH3OH is 0.14 M. Find the equilibrium constant at this temperature.

Answers

Answer:

please check image and explanation

Explanation:

First write the balance chemical reaction

CO(g)+2H2(g)⇌CH3OH(g)

To find out the equilibrium constant first need to find the concentration of each entities at equilibrium.

How many moles of CaO form when 98.60 g CaCO3 decompose

Answers

The balanced reaction is:

CaCO3 = CaO + CO2

We are given the amount of CaCO3 to decompose when heated. This will be our starting point.

98.60 g CaCO3 ( 1 mol CaCO3 / 100.09 grams CaCO3) (1 mol CaO / 1 mol CaCO3 ) ( 56.08 g O2 / 1 mol CaO) = 55.25 g CaO

0.9851mol. This is the rt answer just did it

Mercury has a specific gravity of 13.6. how many milliliters of mercury have a mass of 0.35 kg

Answers

The formula for specific gravity is:

$Specific gravity = (\rho _(substance))/(\rho _(water))$

where $\rho _(substance)$ is the density of the substance and $\rho _(water)$ is the density of water.

The density of water, $\rho _(water)$ = $1 g/mL$

Substituting the values in above formula we get,

$13.6 = (\rho _(substance))/(1)$

$\rho _(substance) = 13.6 g/mL$

The formula of density is:

$density = (mass)/(volume)$

The density of mercury is $13.6 g/mL$

The mass of mercury is $0.35 kg = 0.35 kg * 1000 (g)/(kg) = 350 g$

Substituting the values in density formula:

$13.6 g/mL = (350 g)/(volume)$

$volume = (350 g)/(13.6 g/mL) = 25.73 mL$

The amount, in milliliters, of mercury that will have a mass of 0.35 kg would be 25.74 mL.

If the specific gravity of mercury is 13.6, the density can be obtained such that:

Density of mercury = specific gravity of mercury/density of water

The density of water is 1 g/mL. Thus:

Density of mercury = 13.6/1

= 13.6 g/mL

Also; density = mass/volume

volume = mass/density

= 350/13.6

= 25.74 mL

Thus, the number of milliliters of mercury that will have a mass of 0.35 kg would be 25.74.
